Fix FindBugs warnings in blueprint and enable enforcement
Warnings fixed:
- OpendaylightNamespaceHandler(line 83): "Usage of GetResource may be unsafe
if class is extended". Made the class final so it can't be extended.
- BlueprintContainerRestartServiceImpl(line 140): "return value of this method
should be checked". Log warning if 'await' returns false.
